Michael Bennet, Andrew Romanoff face off for the first time tonight

Before Michael Bennet's fundraiser with President Barack Obama on Thursday afternoon, the incumbent senator has another important date: He and Democratic challenger Andrew Romanoff will meet for their first debate at 8 p.m. tonight.

The faceoff at St. Cajetan's on the Auraria campus (it's sponsored by Denver Young Democrats) should draw a big crowd, since this is the first debate since Romanoff declared he was going after Bennet's seat, and the last before the caucuses a month from now.

Advance tickets are already sold out, but according to the Denver Young Democrats, "a limited number of general admission tickets will also be available at the door with the request of a suggested donation of $15."
